because when the air hole is open it is letting in more oxygen when closed its only got gas to keep it going

What factors affect the rate at which Bunsen burner heats water in a beaker?
tempareture ,nature of the substance and the controller of the bunsen burner
What heats a large amount of liquid science equipment?
I depends on what you class as late but maybe a Bunsen Burner
When a substance is placed over a Bunsen burner it?
typically undergoes heating and may undergo a phase change or chemical reaction depending on its properties. The Bunsen burner provides a consistent and controlled source of heat to increase the temperature of the substance, allowing for various processes such as evaporation, combustion, or decomposition to occur.
What would the Bunsen burner heat on normal flame?
This is a bit like asking what a stove heats in a kitchen. Stoves heat food. Bunsen burners heat chemicals. Chemists have many different chemicals that they sometimes need to heat for various reasons.
What heats a burner flame?
gas
How do the 2011 Toyota Sienna LE heated mirrors work?
A small plate that creates electrical resistance and warms up like a Bunsen burner is located behind the mirror and heats it up to help defrost the mirror.
On a Bunsen burner which flame produces a sooty carbon black deposit on whatever it heats?
I Believe It Is The Roaring But I Am Not Sure. When We Put A Test Tube Into The Roaring Flame, I Think It Turns That Part Black. It May Be The Medium Flame.
What would be the difference in size of crystals between a salt solution that has been evaporated by heating with a Bunsen burner and one that was left to evaporate in normal room temperature?
When you do it on the Bunsen burner it heats quicker so you get a final product sooner. You know it's finished when you start to see white powdery looking stuff around the sides. To wash it run it under cool water and the powder should rinse out with the water.
An instrument that heats small amounts of liquid?
a lighter or or burner.
How is earth's interior like a stove burner?
The core or outer core heats the convection currrents, and therefore is like a stove burner.
What makes the flame of the tirrill burner luminous?
Luminous flames are formed when the energy released is at a certain part of the electromagnetic spectrum. A red flame is given off when the energy is at the same energy and wavelength of red light. A yellow sooty flame is much lower energy and caused by a lack of oxygen. Burning fuels produce heat. Heated atoms and/or molecules emit a photon as they return to a lower energy state. Look at various flames, You may see concentric areas that are like layers, each one a different color. The fuel breaks up or is oxidized differently in each layer and each has a distinct temperature and chemical makeup. Not all emitted light from a flame is visible, a lot is emitted in the infrared spectrum which we cannot see but will feel as it heats our skin. Some flames are totally invisible, like from hydrogen. Some emitted light is only at very specific (narrow) frequencies, which we will see as certain colors, light and dark blue from methane premixed with air in a Bunsen burner or stove-top gas range. Hot carbon atoms emit over a very wide range of frequencies at random, so we see yellow light from candles. If hot enough, carbon emits a bluish white light, like from acetylene/oxygen.
If a burner on the stove heats the bottom of a pot what transfer of heat is ti?
conduction
